Questions about Proco

Are ProCo Rat pedals true bypass?

Early Rat pedals were not true bypass, but later versions (like the Rat 2) are designed with true bypass switching to preserve signal integrity when the effect is disengaged.

Why are Rat pedals so popular?

The Rat's unique distortion character – a blend of fuzz, overdrive, and distortion – provides a thick, saturated tone that’s incredibly versatile and inspiring to many guitarists.

Does ProCo still make amplifiers?

While ProCo historically manufactured amplifiers, their focus shifted primarily to effects pedals decades ago, and they are no longer actively producing amplifiers.
